The new Worx WX279 cordless brushless impact wrench provides the torque you need to remove even old, rusty, large bolts. It employs both rotational force and high frequency tangential blows to deliver an unparalleled amount of torque. It’s comfortable and safe as the high-energy torque is transferred directly to the fastener, not to the operator’s wrist, virtually eliminating any reactionary torque. It features a 3-speed gearbox with variable speed trigger for superior control over output speed and power in a wide range of applications. Such a massive power is packed into just 1.1kg of weight and a tool head length of just 15cm, for maximum comfort in all work applications, including tight spots and overhead operations. ​ This tool is part of the expanding Worx PowerShare, one of the most versatile cordless platforms that covers power tools, lawn and garden tools and everyday life products. PowerShare's "One Battery, Expandable Power" means the same 20V battery can be used in multiple configuration to power up 40V and 80V products.
